Curved mirror 1
A curved mirror is a mirror with a curved reflective surface, which may be either convex (bulging outward) or concave (bulging inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems, like spherical lenses, suffer from spherical aberration. One advantage that mirror optics have over lens optics is that mirrors do not introduce chromatic aberration.
In this worksheet the object is behind the focal point. Now you can change the size of the object, the distance to the mirror and the focal length (move focal point on lot). Write down the effects on the image, when you move these points. When do you get an image with the following attributes
- same size
- reduced (diminished/smaller)
- magnified (larger)
